Howard Glasscock East Unit #31 (API 42-227-35103) is a well in Howard County operated by Apache Corporation, completed April 6, 1999 and listed as shut in on the RRC schedule, shut in May 1, 2020.
The RRC has issued one drilling permit, issued January 10, 1997, permitted to 3,384 ft.
It was permitted by Marathon Oil Company and has since transferred to Apache Corporation on the wellbore schedule.
Completion filings report 6 formation tops, including Seven Rivers, Queen, San Andres, Glorieta.
Its 2 leases have reported 2.08M barrels of oil and 97.3K mcf of gas since January 1998, last reporting volume in April 2026. The leases carry 278 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
